These are my faves right now. Strong likable Mc's. Little to no romance and doesn't have harem (I personally don't like harem I think it ruins it)

I'm looking for a strong mc, no harem, definitely no romance manga/wa/ua.
Tropes like weak to strong, etc.
Also looking for this manga. Boy was isekaid but he came back to his life back in his own world after completing his mission. The thing he woke up upon on was him getting bullied.
